130T punch is a common mechanical equipment in industrial production, processing method for kinetic energy by the punch punching parts, load operation noise more than 90dBA. In our country, the noise of the punch press is as high as 90-110dBA, which has caused great harm to the equipment operator and other personnel in the workshop, and has a great influence on the environment.
In mechanical equipment, the punch noise is very prominent. The research on the noise of the press in the industrial developed countries is carried out earlier, and the development of this work is in the end of 70s. Reduce the punch noise, to consider the quality of processing, productivity, ease of operation and noise reduction costs, and many other factors. It is urgent and difficult to control the noise of the punch press.
